Abstract
Object: We have measured the quantity of static electricity when rayon staple or blended nylon-rayon staple are spun on the cotton spinning system, and investigated how and where static electricity is generated. The effect of static elimination through mechanical methods has been examined comparatively.
Results: (1) The more fiber inte action there is, the larger the quantity of electrification. (2) The quantity of electrification has been reduced from one-fifth to one-fiftieth by the adjustment of temperature and moisture. (3) Spinning is difficult when the quantity of electrification is about 10×10-12 coul/cm2. (4) An anti-static olectric roller and card clothing are useful for preventing electrification. The maximum reduction is about 1/200 in a drawing frame.
